Abstract: 1,233,105. Rectifier control circuits. ALLMANNA SVENSKA ELEKTRISKA A.B. 27 Sept., 1968 [28 Sept., 1967], No. 45936/68. Heading H2F. Individual thyristors, in a high voltage polyphase bridge rectifier (Fig. 1, not shown) comprising a plurality of thyristors in series across voltage distributing networks 11, are fired by pulses from a respective control circuit as shown Fig. 2 and including an auxiliary photo-sensitive thyristor 120, a control pulse energy store capacitor C110, a series resonance circuit L121, C122 to extinguish the auxiliary thyristor, and resistors 123, 124. Capacitor 110 is charged with a positive potential at its upper electrode from the voltage divider network 11 by the "blocked" voltage across the main thyristor Th12 (i.e. the voltage occurring during the blocking period-between zero going positive and the firing instant). When the photo-thyristor 120 receives a light pulse (from a source not shown) it fires and C110 discharges via thyristor 120 producing a firing pulse for the main rectifier thyristor 12. When Th12 fires diode 127 prevents C110 discharging through divider 11 and the anode/cathode of Th12. To prevent C110 being completely discharged after supplying one pulse and so that there will be sufficient energy to provide further pulses should Th12 fail to ignite, the thyristor 120 is turned OFF by the LC circuit the components of which determine the control pulse length. Thus when C110 discharges some of the current therefrom also passes through the LC circuit. When C122 is fully charged it will discharge through L121 and turn OFF Th120 to terminate the control pulse. If Th12 fails to ignite during the first control pulse the "blocked" voltage across it will increase the charge in C110 further ensuring sufficient for a renewed ignition pulse when a new light pulse is sent to Th120. In an alternative embodiment, Fig. 3 (not shown), instead of the photo-thyristor there is provided a photo-conductive device connected to the control electrode of a normal auxiliary thyristor. The control circuitry may be used for a single main thyristor in which case the storage capacitor would be charged from a separate source.

Abstract: 1,257,771. Photo-electric direction finding. ELTRO G.m.b.H. & CO. 24 June, 1966 [6 Aug., 1965], No. 28528/66. Heading H4D. In an optical target detection system, in a rocket tracking head, the received target radiation is modulated by a rotating disc having sectors which alternately transmit and block the radiation. The sighting axis of the optical system of the tracking head is stabilized gyroscopically, by rotation of the tracking head about the optical axis. Prior to firing of the rocket, the optical system is rotated to a high speed above the optical axis. At the instant of firing, the drive to the optical system is switched off and during flight the optical system speed of rotation progressively decreases. To maintain accuracy of detection of target co-ordinates, the speed of rotation of the modulation disc is reduced in correspondence with the fall in the optical system rotational speed. The disc and the rotating optical system are coupled by an A.C. generating circuit, the frequency of which is a function of the optical system rotational speed.

Abstract: 1,259,601. Wave energy position-finding. SEISMOGRAPH SERVICE (ENGLAND) Ltd. 9 Jan., 1969 [9 Jan., 1968], No. 1276/68. Heading H4D. The position of a source of spherical waves emitting a continuous signal containing a constant frequency is determined by measuring, with the aid of a reference signal containing the constant frequency, values of the instantaneous amplitude and polarity of the spherical wave at respective observation points in a linear or an areal array. The source may be real or virtual. In a seismic exploration embodiment (Fig. 6), virtual point sources are produced below subsurface horizons such as RR<SP>1</SP> by reflection of energy from constant frequency vibrator 1. Each point source produces at the surface a respective instantaneous amplitude pattern comprising concentric rings and having a radial distribution of amplitude as shown in Fig. 3, where the pattern centre (r = 0) is vertically above the virtual source. Hence, by locating the pattern centre and determining the radial distribution of amplitude (which is a unique function of the depth of the virtual source) the source can be located in three dimensions. To this end, values of the phase # (relative to the seismic signal generated by vibrator 1) and periodic peak amplitude A of the reflected signal at observation points in an array are recorded using mobile receiver unit 12. A pair of detectors 10, 11 at half-wavelength spacing is used to give cancellation of the direct (surface) wave signal in their combined output. Detector 4 and a radio link 5, 6 provide a phase reference signal for synchronous rectifier 7. The instantaneous amplitude a is obtained from the relation a = A sin #. Alternatively a lock-in amplifier can provide a D.C. output proportional to a. Noise is eliminated by filter 9, which may be of the resonant type or one in which the filter input is crosscorrelated with a sample of the reference signal. The amplitude patterns may be recorded in variable-area or variable-density form or on magnetic tape or punched cards. To determine the virtual source positions the patterns are compared with reference patterns representing sources of known position, by cross-correlation in an analogue device (e.g. optical) or digital processing system (details given); alternatively the positions are found by computation from the measured radial distribution of amplitude. In an embodiment for locating a real sound source in the form of a break in a buried water-pipe, vibrator 1 is not needed and the reference signal is provided by a detector at an arbitrary fixed position on the earth's surface. The invention may be used to locate radio wave sources and is applicable to ionospheric sounding.

In the embodiment of Fig. I one end of the belt 1 is attached to a screw 4 held by an eye 5 which is mounted on a metal strip 6 located by deformable lugs 8, 9 behind a rectangular opening 7 in the bodywork such that when an excessive pull is applied to the belt the metal strip is deformed and at least partially pulled through the opening 7 thus absorbing energy. The opening is preferably wider than the strip and its edges 10 may be covered by a plastics material to enhance friction. In an alternative embodiment as in Fig. 3 the eye is attached to one end of a perforated strip forming part of the bodywork, the strip being torn partly out of the bodywork when a forceful pull is applied to the belt.
